The N-methyl-D-aspartate receptor (NMDAR) is an ion channel that mediates the slow, Ca2+-permeable component of glutamatergic synaptic transmission in the central nervous system (CNS). NMDARs are known to play a significant role in basic neurol. functions, and their dysfunction has been implicated in several CNS disorders. Herein, we report the discovery of second-generation GluN2C/D-selective NMDAR-pos. allosteric modulators (PAMs) with a dihydropyrrolo[1,2-a]pyrazin-3(4H)-one core. The prototype, R-(+)-EU-1180-453, exhibits log unit improvements in the concentration needed to double receptor response, lipophilic efficiency, and aqueous solubility, and lowers cLogP by one log unit compared to the first-generation prototype CIQ. Addnl., R-(+)-EU-1180-453 was found to increase glutamate potency 2-fold, increase the response to maximally effective concentration of agonist 4-fold, and the racemate is brain-penetrant. These compounds are useful second-generation in vitro tools and a promising step toward in vivo tools for the study of pos. modulation of GluN2C- and GluN2D-containing NMDA receptors.

554-01-8, 5-Methylcytosine is a methylated form of the nucleobase cytosine occurring predominantly in cytosine-phosphate-guanine (CpG) islands that are produced by DNA methyltransferases and may regulate gene expression. Like cytosine, the DNA sequence containing 5-methylcytosine (5-mC) is able to be replicated without error and 5-mC can pair with guanine in double stranded DNA. However, DNA sequences containing a high local concentration of 5-mC may be less transcriptionally active than areas with higher ratios of unmodified cytosine.
5-Methylcytosine belongs to the class of organic compounds known as hydroxypyrimidines. These are organic compounds containing a hydroxyl group attached to a pyrimidine ring. Pyrimidine is a 6-membered ring consisting of four carbon atoms and two nitrogen centers at the 1- and 3- ring positions. 5-Methylcytosine exists as a solid, slightly soluble (in water), and a very weakly acidic compound (based on its pKa). Within the cell, 5-methylcytosine is primarily located in the cytoplasm. 5-Methylcytosine can be biosynthesized from cytosine. Outside of the human body, 5-methylcytosine can be found in tea. This makes 5-methylcytosine a potential biomarker for the consumption of this food product.
5-methylcytosine is a pyrimidine that is a derivative of cytosine, having a methyl group at the 5-position. It has a role as a human metabolite. It is a member of pyrimidines and a methylcytosine. It derives from a cytosine.
5-Methylcytosine is a nucleic acid that is found in the DNA and RNA of the cell. It is an important component of methylation, which is the process by which a methyl group is added to a molecule. This process can lead to cellular transformation, a process that can cause cancer. 5-Methylcytosine has also been shown as a molecular pathogenesis factor in infectious diseases such as HIV and herpes simplex virus type 1. The presence of 5-methylcytosine in nuclear DNA has been detected by analytical techniques such as gas chromatography/mass spectrometry (GC/MS). There are many analytical methods, including GC/MS, that can be used to detect 5-methylcytosine in cellular nuclei., Recommanded Product: 4-Amino-5-methylpyrimidin-2(1H)-one

Inaki;Arimondo, Paola B. research published 《 Identification of Chemical Probes Targeting MBD2》, the research content is summarized as follows. Epigenetics has received much attention in the past decade. Many insights on epigenetic (dys)regulation in diseases have been obtained, and clin. therapies targeting them are in place. However, the readers of the epigenetic marks are lacking enlightenment behind this revolution, and it is poorly understood how DNA methylation is being read and translated to chromatin function and cellular responses. Chem. probes targeting the methyl-CpG readers, such as the methyl-CpG binding domain proteins (MBDs), could be used to study this mechanism. We have designed analogs of 5-methylcytosine to probe the MBD domain of human MBD2. By setting up a protein thermal shift assay and an AlphaScreen-based test, we were able to identify three fragments that bind MBD2 alone and disrupt the MBD2-methylated DNA interactions. Two-dimensional NMR experiments and virtual docking gave valuable insights into the interaction of the ligands with the protein showing that the compounds interact with residues that are important for DNA recognition. These constitute the starting point for the design of potent chem. probes for MBD proteins.

Fang, Tianjiao;Tang, Chao;Yin, Junfa;Wang, Hailin research published 《 Magnetic multi-enzyme cascade combined with liquid chromatography tandem mass spectrometry for fast DNA digestion and quantitative analysis of 5-hydroxymethylcytosine in genome of human bladder cancer T24 cells induced by tetrachlorobenzoquinone》, the research content is summarized as follows. Long-term exposure to halobenzoquinones (HBQs) can induce genomic damages and abnormal epigenetic modifications. High-performance liquid chromatog. tandem mass spectrometry (HPLC-MS/MS) has shown unique advantages in identification and sensitive anal. of these structurally modified DNA lesions. Prior to MS anal., genomic DNA needs to be fully digested into mono-nucleosides. Here, we prepared Supernuclease (SN)-, snake venom phosphodiesterase (SVP)- and calf intestinal alk. phosphatase (CIP)- individually immobilized magnetic nanoparticles (MNPs), and combined them according to certain formula to construct a recyclable SN-SVP-CIP magnetic nanoparticles (SNSC-MNPs) cascade for rapid and efficient DNA digestion. The SNSC-MNPs cascade can fully digest genomic DNA into mono-nucleosides within 30 min. The SNSC-MNPs cascade coupled with HPLC-MS/MS method can accurately and sensitively detect 5-hydroxymethylcytosine (5hmC) changes in genome of human bladder cancer T24 cells induced by tetrachlorobenzoquinone. The immobilization of enzymes on MNPs can enhance the stability and enzymic activity of the three enzymes, which guarantees the reusability and longtime preservation of the cascades. The relative digestive efficiencies are among 86% -106% up to ten times of reuse. The newly synthesized SNSC-MNPs cascade coupled with HPLC-MS/MS method is promising for fast identification and anal. of structural modifications in genomic DNA.

Fang, Xiaojie;Miao, Chenyun;Zeng, Tianni;Chu, Weijian;Zheng, Yi;Sun, Xi;Yin, Xin;Li, Yanyan research published 《 Role of m5C RNA methylation regulators in colorectal cancer prognosis and immune microenvironment》, the research content is summarized as follows. RNA modification has become one of the hot topics of research as it can be used for tumor prognosis. However, its role in various biol. processes is still poorly understood. The aim of this study was to investigate the role of m5C and m1A regulators on colorectal cancer prognosis using bioinformatics tools. The association between these regulators and differences in patient survival as well as the clinicopathol. characteristics and tumor immune microenvironment in colorectal cancer tissues were assessed. We selected publicly available colorectal cancer data sets from The Cancer Genome Atlas and used the “limma” package in R to identify differentially expressed genes. The least absolute shrinkage and selection operator regression model was used to calculate the prognostic risk, and a risk prediction model was constructed, to help assess the prognostic values of the differentially expressed genes. Finally, using TISCH and TIMER, we assessed the extent of cellular infiltration in colorectal cancer. We explored NSUN6 and DNMT3A expression using UALCAN and HPA and found that their expression is significantly increased in colorectal cancer tissues and correlated with sex and TP53 mutation status. Moreover, we found NSUN6 and DNMT3A were related to the infiltration of six major immune cells, with DNMT3A being closely related to dendritic cells, CD4+ T cells, and B cells, whereas NSUN6 to B cells and CD8+ T cells. Our findings suggest that m5C regulators can predict the clin. prognostic risk and regulate the tumor immune microenvironment in colorectal cancer.

The nomenclature of pyrimidines is straightforward. However, like other heterocyclics, tautomeric hydroxyl groups yield complications since they exist primarily in the cyclic amide form. 1722-12-9, formula is C4H3ClN2, Name is 2-Chloropyrimidine. For example, 2-hydroxypyrimidine is more properly named 2-pyrimidone. A partial list of trivial names of various pyrimidines exists. Recommanded Product: 2-Chloropyrimidine.

Das, Dharmendra;Bhosle, Akhil A.;Panjikar, Padmini C.;Chatterjee, Amrita;Banerjee, Mainak research published 《 Mn(I)-Catalyzed Mechanochemical C-H Bond Activation: C-2 Selective Alkenylation of Indoles》, the research content is summarized as follows. An efficient mechanochem. method for manganese-catalyzed regioselective C-H bond alkenylation of indoles with alkynes is developed. The present method allows direct C-2 alkenylation of indoles in a mixer mill, employing a com. available low-valent manganese catalyst, MnBr(CO)5, providing a sustainable route to hydroindolation on alkynes. The developed protocol is highly C-2-selective by the presence of a heteroaromatic N atom as a directing group (namely, pyridyl) and tolerant of structural variations with electron-rich and electron-deficient substituents both in the indoles and in the alkynes. Silica as the grinding media and the presence of a catalytic amount of acid and DIPEA as the base worked favorably to afford a variety of 2-alkenyl indoles in excellent yields at ambient conditions. The terminal alkynes offered better results than internal alkynes in terms of yields and reactivity. The scalability of the reaction was demonstrated by conducting the reactions in the gram scale. A short study indicated that a little tweak in conditions can be useful for double alkenylation to afford carbazole derivatives in moderate yields. A low E-factor along with a clean reaction profile, an easy exptl. setup, the absence of an anhydrous condition, and being devoid of toxic organic solvents proclaims its advantage over the available conventional methods.

Category: pyrimidines, 5-Methylcytosine is a methylated form of the nucleobase cytosine occurring predominantly in cytosine-phosphate-guanine (CpG) islands that are produced by DNA methyltransferases and may regulate gene expression. Like cytosine, the DNA sequence containing 5-methylcytosine (5-mC) is able to be replicated without error and 5-mC can pair with guanine in double stranded DNA. However, DNA sequences containing a high local concentration of 5-mC may be less transcriptionally active than areas with higher ratios of unmodified cytosine.
5-Methylcytosine belongs to the class of organic compounds known as hydroxypyrimidines. These are organic compounds containing a hydroxyl group attached to a pyrimidine ring. Pyrimidine is a 6-membered ring consisting of four carbon atoms and two nitrogen centers at the 1- and 3- ring positions. 5-Methylcytosine exists as a solid, slightly soluble (in water), and a very weakly acidic compound (based on its pKa). Within the cell, 5-methylcytosine is primarily located in the cytoplasm. 5-Methylcytosine can be biosynthesized from cytosine. Outside of the human body, 5-methylcytosine can be found in tea. This makes 5-methylcytosine a potential biomarker for the consumption of this food product.
5-methylcytosine is a pyrimidine that is a derivative of cytosine, having a methyl group at the 5-position. It has a role as a human metabolite. It is a member of pyrimidines and a methylcytosine. It derives from a cytosine.
5-Methylcytosine is a nucleic acid that is found in the DNA and RNA of the cell. It is an important component of methylation, which is the process by which a methyl group is added to a molecule. This process can lead to cellular transformation, a process that can cause cancer. 5-Methylcytosine has also been shown as a molecular pathogenesis factor in infectious diseases such as HIV and herpes simplex virus type 1. The presence of 5-methylcytosine in nuclear DNA has been detected by analytical techniques such as gas chromatography/mass spectrometry (GC/MS). There are many analytical methods, including GC/MS, that can be used to detect 5-methylcytosine in cellular nuclei., 554-01-8.

The systematic study of pyrimidines began in 1884 with Pinner, who synthesized derivatives by condensing ethyl acetoacetate with amidines.

Abstract: Aggressive and metastatic cancers show enhanced metabolic plasticity1, but the precise underlying mechanisms of this remain unclear. Here we show how two NOP2/Sun RNA methyltransferase 3 (NSUN3)-dependent RNA modifications-5-methylcytosine (m5C) and its derivative 5-formylcytosine (f5C) (references2-4)-drive the translation of mitochondrial mRNA to power metastasis. Translation of mitochondrially encoded subunits of the oxidative phosphorylation complex depends on the formation of m5C at position 34 in mitochondrial tRNAMet. m5C-deficient human oral cancer cells exhibit increased levels of glycolysis and changes in their mitochondrial function that do not affect cell viability or primary tumor growth in vivo; however, metabolic plasticity is severely impaired as mitochondrial m5C-deficient tumors do not metastasize efficiently. We discovered that CD36-dependent non-dividing, metastasis-initiating tumor cells require mitochondrial m5C to activate invasion and dissemination. Moreover, a mitochondria-driven gene signature in patients with head and neck cancer is predictive for metastasis and disease progression. Finally, we confirm that this metabolic switch that allows the metastasis of tumor cells can be pharmacol. targeted through the inhibition of mitochondrial mRNA translation in vivo. Together, our results reveal that site-specific mitochondrial RNA modifications could be therapeutic targets to combat metastasis.
